		sybrenUnsubmitted Done Inline Actions A ratio between 0 and `FLT_MAX` is weird. How can you remove more than 100% of the points? It's also unclear what the ratio indicates. What would ratio=0.2 do? Remove 20% of the points? Or keep 20% of the points? I've tried it with the default ratio, and it removed all the points except the first and last one, even though there were quite big jumps in the curve. sybren: A ratio between 0 and `FLT_MAX` is weird.

		sybrenUnsubmitted Done Inline Actions This still needs a description explaining what 'ratio' means. Right now it's unclear (it doesn't even say it's about the number of keyframes), and it's ambiguous whether this is the percentage to keep or the percentage to remove. Since the default value is 50%, you can't even tell which one it is from the result, as removing 50% is the same as retaining 50%. sybren: This still needs a description explaining what 'ratio' means.
